Corrosion Failure Analysis of an SA210 Steel Used in High Pressure Evaporator Tube of the Gas Heat Recovery Boiler

Abstract:

The corrosion failure analysis of an SA210 steel used in high pressure evaporator tube is conducted by XRD, SEM, OM. The result shows that the corrosion products in the inner wall of the steel tube is Fe3O4, mainly caused by the residual water in the evaporator tube corroding its inner wall with oxygen after the hydrostatic test of the boiler, finally leading to the corrosion leak of the tube.
